Detailed Description

Many industrial processed liquids become contaminated with various solids, debris or swarf causing detrimental effects to the process involved. This deep bed gravity filter provides effective deep bed gravity filtration to remove these contaminants Operation: 1) The dirty liquid to be clarified is either pumped or followed by gravity into the top inlet of filter 2) Liquid passes through the low velocity inlet distribution header, where it is discharged into the bed of filter 3) A layer of disposable filter media is positioned within the filter, and is supported By a flat wire conveyor belt 4) As the dirty liquid passes through the filter, solids are removed by the disposable filter media, allowing only the clean liquid to pass through, which drains out of the bottom of filter by gravity 5) Solids accumulate on the surface of media to form a filter "cake", which further improves filtrate clarity through depth filtration 6) The inlet header is submerged in the liquid pool to minimize disturbance of the filter "cake", and foaming of the liquid 7) Filter also includes Keeyun's patented labyrinth type positive side seal design, which creates a double-side seal to prevent migration of solids around the edge of the filter media 8) Over time the filter "cake" becomes thicker and more dense, such that the filtrate rate through the media decreases causing the level of liquid pool to rise 9) This is sensed by a level control float, which then automatically indexes the dirty media out of the filter in short increments, while also introducing fresh media into the filter 10) The liquid level drops whereby indexing is stopped, thus providing for completely automatic operation 11) To help prevent the roll of filter media from running out, this type of filter Is equipped with an end-of-media switch, which senses when the media roll is almost depleted, and annunciates an alarm condition on the filter control panel
